DRAW-HOOK AND DRAW-BAR FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 769,793, datedSeptember 13, 1904.

Application filed May 5, 1904. Serial No. 206,521. (No model.)

To all whom, it may concern.-

Be it known that I, PHILLIP D. DOYLE, a citizen of the United States,residing in Somerville, in the county of Middlesex and State ofMassachusetts, have invented a new and Improved Draw-Hook and Draw-Barfor VVagons, of which the following is a specification.

This inventionrelates to draw-hooks and draw-bars for double wagons,mostly wagons used for teaming purposes.

As heretofore constructed, as far as I am aware, the draw-hooks anddraw-bars are made in a single integral piece or from two pieces, whichare afterward welded together, so that the hook and bar are, when readyfor use, practically a single integral piece. The wear produced by thewhiflietree is of course on the hook and in practice on a particularportion of the hook. When this portion of the hook is worn nearlythrough, the entire drawhook and draw-bar are useless, and a new hookmust be substituted for the old one.

It is the particular object of this invention to produce a draw-hook anddraw-bar which is separable, whereby when the hook becomes worn it canbe removed from the draw-bar without disturbing the latter or itsposition on the wagon-gear and anew hook substituted.

The nature of the invention is fully described below, and illustrated inthe accompanying drawings, in which Figure 1 is a side elevation of aportion of. 'a gear of a wagon and a cross vertical section of theforward axle with my improved drawhook and draw-bar shown in position inelevation. A portion of the pole is also illustrated. Fig. 2 is a planView of the same, taken on line 2 2, Fig. I. Fig. 8 is an enlarged planView of the invention, a portion of the bar being broken off. Fig. 4 isa cross section taken through the cross bar and a longitudinal sectiontaken on line L 4, Fig. 3.

Similar letters of reference indicate corresponding parts.

represents an ordinary frame of the gear of a wagon, 5 being thefifth-wheel. c is the pole, (Z the front axle, and c the cross-bar, allconstructed as usual.

Secured to the front axle d by means of a clip f and suitable nuts g,near each end of the axle d, is a draw-bar 71, the front end h of whichis thickened downwardly and is integral with the main portion h. Thismain portion extends upward at an angle, as shown in Fig. 1, from theunder side of the axle,-and,

the front end or head it is provided next its upper surface withoppositely extending wings 7L, Fig. 3, by means of which the draw-bar issecured to the cross-bar e by suitable bolts .9. Thedownwardly-extending portion it of the draw-bar is provided with ahorizontal hole, through which the squared shank Z of the hook 71extends, the shank fitting in the said hole, and thereby preventingrotation.

The rear end of the shank is screw-threaded to receive a nut 12, whichmay be locked in place, if desired, as shown in Fig. 4. The draw-hooks,draw-bars, and their connecting means are exactly alike and are appliedto the cross-bar in the usual locations.

It will readily be seen that when a hook it has become so much worn thatit is no longer safe or strong the nut n can be removed and the shank Zwithdrawn from the portion IL and the shank of a new hook inserted. Thusit is not necessary to remove and lose the draw-bar, as is the case whenthe draw-bar and hook are in a single piece.

The advantage of this construction is evident when it is considered thatpractically all the wear is on the hook and that a single drawbar willoutwear many draw-hooks.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is*

1. In adraw-hook and draw-bar for wagons, the draw-bar h formed at itsforward end with the thickened head it; and the draw-hook 7r; removablysecured in and extending forward from said head, for the purpose setforth.

2. In a draw-hook and draw-bar for wagons, the draw-bar it formed at itsforward end with the thickened head h, and provided at said end with theoppositely-extending wings it", whereby the draw-bar may be secured tothe under side of the cross-bar making a portion of the wagon-gear; andthe draw-hook provided with the shank Z removably secured in andextending forward from said head, for to this specification in thepresence of two subthe purpose set forth. scribing witnesses.

3. A separable draw-hook and draw-bar for wagons, the shank of saiddraw-hook being 5 removably secured to'the forward end of the Witnesses:

draw-bar, for the purpose set forth. HENRY W. WILLIAMs,

In testimony whereof lhave signed my name A. K. HOOD.
